Functional and Physiological Effects of Treadmill Training Induced by Buspirone, Carbidopa, and L-DOPA in Clenbuterol-Treated Paraplegic Mice
Bibliographic record
Abstract
BACKGROUND: Chronic spinal cord injury may be complicated by weight loss, muscle atrophy, and bone loss. OBJECTIVE: The authors identified a combination pharmacotherapy using buspirone, carbidopa, and L-DOPA (BCD) that elicits bouts of locomotor-like movements in spinal cord-transected (Tx) mice. They then evaluated the effects of 8 weeks of treadmill training in Tx mice that received BCD or BCD + clenbuterol, a monoaminergic agent with anabolic properties, on locomotor function, muscle atrophy, adipose tissue loss, and bone density measures. METHODS: Induced locomotor movement, adipose tissue, skeletal muscle, and femoral bone properties were compared in unoperated control mice, operated controls (untreated, untrained Tx mice), and 2 groups of treated, trained Tx mice (Tx + BCD, Tx + BCD + clenbuterol) that also received training. RESULTS: BCD- and BCD + clenbuterol-treated mice showed comparable levels of locomotor movements that significantly improved over time. Soleus muscle mass and soleus and extensor digitorum longus cross-sectional area significantly increased in both groups of BCD-treated mice, with greater effects in BCD + clenbuterol-treated animals. Fiber type conversion, adipose tissues, bone mineral density, and content were reduced in all Tx groups compared with unoperated control mice. CONCLUSION: These findings suggest that locomotor movement and muscle properties can be restored to near-normal levels after several weeks of BCD treatment, regular training, and clenbuterol in completely paraplegic animals.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
